Battery Life
The Lumia 925 is powered by a non-removable Li-Ion 2000 mAh battery, which provides an adequate standby time of up to 440 hours on 3G and a talk time of up to 18 hours and 20 minutes on 2G networks. Additionally, music lovers could enjoy up to 55 hours of music playtime, which is impressive. Despite its relatively small battery capacity by modern standards, it provided reasonable longevity for typical day-long usage patterns when first released.
